Hey guys! This is all new to me! I just got my OBDII bluetooth dongle and I have started with Torque Lite App. I want to start logging my commutes. I am a car guy and I love the numbers game. What I need from you gurus are the numbers I should take a look at to verify a healthy stock setup.

 

Which of the MANY parameters are you intending to log?

 

That was part of my question. I am unsure what I need to log and what numbers I need to compare them to to verify optimal oem performance metrics. I logged my commute to work this morning! I logged Engine RPM, Engine Load, and Throttle Position. The G forces, GPS speed, and time are logged automatically. I have over 20 thousand data points from my commute and I ABSOLUTELY LOVE ALL THE NUMBERS!!!!!!!!!

I included a few rows here sorted by G force due to acceleration or deceleration (+ or -). I sorted the g force column from largest to smallest and noticed that my hardest physical pull was at

• 53 mph
• 1788 rpm
• 14% throttle
• 29.4% engine load

The image below includes my 10 hardest pulls based on G forces.

 

Fuel trims vs load might be an interesting statistic to look at.

 

I will add those!
